Note
At output amplitudes of <50 mV in extreme environmental
4
conditions, it is recommended you use a double shielded BNC cable.
For example, use
HP p/n 5180-2459 (1.22 m, RG58V Triax, 500).
High-Voltage Option (Output Amplifier :OUTPut:AMPLify)
When the high-voltage output is used (option 001 is installed),
a maximum output of 40
V peak-to-peak is available into a high
impedance. The load resistance must be more than 5000 or
distortion will result, particularly at higher frequencies. To ensure
square wave overshoot of <5% of the peak-to-peak output, the total
capacitance connected to the output should be
<500 pF. An error
will occur if the amplitude is given in dBm for the high-voltage
option.
The amplitude limits for the high-voltage option are shown
in Table
4-3. The ranges given, are only applicable when no DC offset has
been specified. When this is the case, see Table 4-4.
Note
When the high-voltage option is switched on, the output
3
amplitude/offset "jumps" to its 4-fold value. When it is switched off,
it is automatically decreased by a factor of four.
For example, the
amplitude=l V(p-p). Turning the high-voltage
on causes the amplitude output to be 4 V(p-p). Turning the
high-voltage off causes the amplitude output to be
1 V(p-p) again.
